Covert spy station

Very important spy centre can be found at the unassuming location of Irton Moor, near the quaint seaside town of Scarborough. Back bench MPs in successive governments have failed gloriously in trying to find out precisely what goes on at this base, which MI5/6 operatives refer to as simply "Scarborough".

The 1:25000 OS map gives the full detail and labels it with the rather romantic title "Wireless Station". It dates back to the very early pre-WWII days of GCHQ, when that was known as the Government Codes and Ciphers School (GC&CS). Irton Moor is sometimes referred to as a Composite Signals Organisation (CSO) station.
